Need to shut down two or three open programs quickly, but leave the rest running? Hold down the CTRL key as you click their buttons on the taskbar. Then, right-click (still holding down the CTRL key) one of those depressed buttons and select “Close” from the resulting menu. Poof! They’re all gone!
Note: There are other functions you can do, too! You can also minimize, maximize, restore, cascade, or tile these windows using this technique. Cool huh?
